Three-Quarters Binding

 A binding in which the spine and corners are generously covered with leather. The rest of the binding material is different, i.e., cloth, marbled paper, another type of leather.

Tight Back

 The book that is bound very tight with an inflexible spine, almost to a fault because when it opens, the pages will not lie flat by themselves. However, as the book becomes well used, the binding will eventually loosen. The use of the tight back declined dramatically after about 1820, except by fine binders who often used it along with false raised bands. Also known as fast back.

Tipped-In

 A publisher-authorized content correction that is made after a book has been printed and bound. It can be as small as a scrap of paper to correct type, or as large as a page or a signature to correct a section. The corrected page or illustration is glued onto the page or inserted into an already bound book. They are less common today with the advanced printing techniques, but were very common in the 17th and 18th centuries due to numerous printer errors. Also known as cancels.
